Study Notes
Chapter 1: Introduction to Applied Sport Mechanics (PE 4283: Sport Biomechanics)
- Course aims to explain how the human body moves.
- Course aims to explain how mechanical principles improve athletic performance.
- Course aims to explain how mechanical principles apply to sports.
- Course aims to explain how to use sport mechanics to assess sport technique.
Chapter Organization (Part 1)
- Part 1 covers the foundations of movement in sport.
- Contains 10 chapters, starting with sport mechanics anatomy (chapter 2).
- Next topics include sport mechanics fundamentals, linear motion and kinetics, angular motion and kinetics, stability and instability, sport kinetics, and moving through fluids.
Chapter Organization (Part 2)
- Part 2 provides the application of sport mechanics.
- Includes 3 chapters focusing on applying the learned concepts: analyzing sport skills, identifying and correcting errors, and selected sport skills.
Surprising Facts on World Records
- Some records have greatly improved with modern technology while others have remained stable for decades.
- Pole vaulting records have changed significantly.
- High jump records have also seen some improvement.
How Applied Sport Mechanics Can Help
- Provides understanding of physical laws influencing athletic performance.
- Helps analyze, and immediately recognize, how athletes' movements can be improved.
- Understanding external forces that athletes encounter during performance.
- Helps analyze the efficiency of movements.
What is Applied Sport Mechanics?
- Understanding mechanical principles applied to sport and exercise.
- Aims to improve sports technique, safety, and performance.
- Biomechanics assesses forces on humans in sports.
- Biomechanics analyses forces generated by humans.
- Applications in the study of biological systems, including walking/running analysis (force application).
Level Systems (1st, 2nd, 3rd)
- Diagrams of skeletal and muscle systems, illustrating force application.
What is Applied Sport Mechanics? (Continued)
- Basic laws of force and motion apply to human movement.
- Includes linear and angular kinematics and kinetics.
- Covers concepts like forces, laws of motion, center of mass, torque, and moments of inertia.
Understanding and Quantifying Technique (Part I)
- Technique is best described by the pattern and sequence of movements, in order to perform a sport skill.
- Must distinguish between safe, mechanically correct movements and those that serve no purpose.
Advances in Equipment Require Changes in Technique
- Equipment advances often require athletes to adopt new techniques.
- Examples such as speed skating, where new blade designs call for specific changes in technique.
Understanding and Quantifying Technique (Part II)
-
Skills can be categorized as either "closed" skills or "open" skills, determined by whether the environment the athlete interacts with remains constant.
-
Closed skills: The environment doesn't change during the performance of the skill. Examples: discus throw.
-
Open skills: The environment changes during the performance of the skill. Examples: tennis serve.
Measuring and Analyzing Technique
- Quantitative measures use numbers (e.g., speed, distance).
- Qualitative measures describe the quality of the movement using descriptive words (e.g., smooth, efficient).
Never Discount Individual Creativity and Inventiveness
- Innovations by athletes can revolutionize a sport.
- Exemplified by Graeme O'Bree's innovative cycling design that reduced air resistance and potentially improved performance despite not being legal at the time.
Teaching Good Technique
- Demonstrating good technique is helpful but not always essential.
- More crucial is identifying and correcting errors.
- Teaching progressions are key to moving novices towards more refined performance.
Summary: Applied Sport Mechanics
- Provides scientific understanding of how and why mechanical principles produce improved performance.
- Involves linear & angular kinematic analysis.
- Includes concepts of position, displacement, velocity, acceleration, linear/angular kinetics, forces, laws of motion, centre of mass, torque, and moments of inertia.
Summary: Technique
- Technique involves the pattern/sequence of movements used to perform a sport skill.
- Quantitative measures use numerical data (e.g., speed).
- Qualitative measures describe the quality/characteristics of the movement (e.g., coordination, fluidity).
